Disentangling Interacting Symmetry-Protected Phases of Fermions in Two Dimensions
We construct fixed point lattice models for group supercohomology symmetry-protected topological phases of fermions (2+1)D. A key feature of our approach is to construct finite depth circuits of local unitaries that explicitly build the ground states from a tensor product state. We then recover the...
